METHOD or rLL'osrnA'rrorr.

Patented Feb. 2li, i922..

Y Application led May 16,1921.- Selial No. 470,029.

Be it known that I, ROBERT PHEN, a citizen of the United States, residing at Newark in. the county of Essex and State of New .ler-sey, have invented certain new and useful Improvements in Methods of Illustration, of which the following is a specification.

This invention relates to the preparatlon of drawings of inventions and associated matters such as trade-marks and designs and its object is to illustrate them more clearly or in a more life-like manner than is vat present the custom in official Patent Oiiice drawings. u

The invention consists essentially 1n using the customary bristol board sheets or other translucent material and applylng to one side thereof a drawing of the invention 1n black ink which shows the usual views with all ltheir detaily and then a plying to the side of the sheet additiona views, preferably in color registering with the views on the front of the sheet whereby when the sheet is viewed by reflected light lthe usual sdrawing in black appears but when the sheetl is viewed by transmitted llght, the composite View appears. in other 'words one aspect of the invention is applied to one side of the sheet and another aspect ofthe invention is applied to 'tliegback of the sheet with the twovr views registering.

The invention is capable of many'fembodiments but only one or two are herein set forth and therefore they. are to be taken as being illustrative and not as llmlted. With this in mind, the invention has been illustrated in the accompanying drawlngs iny whichi `Figure 1 shows perspectively the effect produced when viewing a drawing made according to this invention;

Figure 2 shows a side elevation of a sheet made according to this invention;

Figure 3 shows the front and back of such v a sheet, as also doesFigure 4;

Figure 5 shows how spectrum lines may be used; Y

Figures '6 to 12 show partial vertical sectionsl of sheets embodying modifications .of

the invention;

Fig. 173. shows how the effect of whole View A14 l showanother aspect of the invention 15, preferably in color sothat the front face of the drawing shows the black ink aspect while the back of the sheet shows the color as illustrated in Figure 3. Instead of color on the back sheet, the second aspect which may be in blackand this second aspect is indicated at 16 on the back of the sheet in Figure 4.

The second aspect in this' case is the appearance' of liquid and the refraction of the rod is on the back so that when the sheet is viewed by transmitted light a complete picture is seen. The same is true of the drawing in Figure 3. Whenthe sheet is placed on a table or other support face up, only the black ink drawing 14 isseen, but asthe'sheet is raised as shown in Figure 1 from the position on the table A in Figure 1, through the pofsitions B- to C and therefore the change from viewing the drawing by refiected light in the position A to viewing it by transmitted light, changes the picture from a simple black drawing to a composite drawing of the black drawing on the face and the colored or other aspect on the back of the sheet which is in register with that on the front. v i

Figure 2 shows diagrammatically, a sheet to which the coloring 15 is applied to the back. Effects of illuminationA or electric discharges can be produced by removing a gart of theiback of the sheet as at 17. everal colors can be superposed upon the back of the sheet as at 18 and a combination of removing a part of the sheet and superposed colors is shown at 19. Further, the colors or second aspect of the invention 15 can be placed between two plys of paper. 21 and 22 or one part'23 ot the coloring can be placed between two plys 21 and .22 of a sheet and another part 24 of the color 17 can be on a middle ply 22.

The illusion of rotation can be produced by putting a spiral 26 or a plurality of curved lines on .the back of a sheet 1n register with the black ink drawing 27 on the front of the sheet which it is desired to have appear to rotate. That is, a construction of Vthis character appears to rotate when v the drawing is viewed by transmitted light and a light rotary motln is imparted to the sheet. llilervescence may be shown by making pin or other pricks 'through 'the sheet or by applying small circles on the back of the sheet.

The chemical action can be showntaking place in an apparatus by means of various colors applied to the back of the sheet and the chemical form can be indicated by using its spectrum color or lines as shown at 28' in Figure 5. By the properpositioning of the spectrum lines either to the right or left, the `chemical may be shown to be advancing or retreating. In Fig. 13.is illustrated how one part of a view can be shown at 29 when the sheet is, viewedby reiiected light in theposition A, and that as the sheet is moved through the position B toC where it is seen en'- tirely by transmitted vlight. Another part 0f a View .comes into rominence gradually until 1n the position' the composite view isseen made up of the two parts 29 and 30.

lt can thus be seen that by the use of this process, drawings can be made to show many things and actions which have hitherto been considered diiheult, if not impossible to illustrate. For instance, Patent Office ldrawings of trade-marks can by the use of transmitted light, show 'the trade-mark in its characteristic colorings. ln the same way, drawings of designs, such as rugs, textiles, china ware., etc., can be made to show the actual coloring of the design or pattern.

ln patent drawings, covering woven or knitted fabrics, the individual threads can be easily followed by having a separate color applied to each. In complicated mechanical cases having many views, each train of `associated elements can be given lthe same color in 'each view to make much leasler the following of the drawing.

electrical cases, sparks, arcs or any other lighting effect can be shown by removing a. part of the sheet from the back so that more transmitted light will pass through the sheet in the thinned area. In chemical cases, the chemical change can b'e shown,

Inl

f or by pin or other pricks through the sheet.

Moreover, phantom Views may be obtained by showing an interior construction on one side of the sheet and the casing or other enclosing construction on the other side of the sheet in proper register. Again, a cross sectional or face view of an element can be shown on one side of the sheet and a prospective or length (or width) view of that element shown on the other side of the sheet and in register. Further, a part or element may be made to appear to rotate by lacing on the back of the sheetand in register therewith, a spiral, or intersecting spirals, whereby when the sheet is moved slightly the illusion is produced of'rotation of the element.

The invention .has been primarily devised for the roduction of drawings for the Patent 0 ce, but it is capable of being used to make illustrations of many kinds of inventions or other things for catalogue work, advertisement instruction, education and the like and the claims should be read in the light of this use.
